Implant-specific follow-up imaging of treated intracranial aneurysms: TOF-MRA vs. metal artifact reduced intravenous flat panel computed tomography a…

2017

Aim To compare the diagnostic quality of time-of-flight magnetic resonance angiography (TOF-MRA) and metal-artefact-reduction (MAR) flat-panel-detector computed tomography angiography (FPCTA) and to determine the imaging technique best suited for evaluation endovascular and surgically treated aneurysms. Methods The image quality of TOF-MRA and MAR-FPCTA of 44 intracranial implants (coiling: n= 20; clipping: n= 15; coiling + stenting: n= 9) in a patient cohort of 25 was evaluated by two independent readers. Images obtained using MAR-FPCTA (20 second scan time, 496 projections, intravenous contrast medium administration; Artis Zee, Siemens Healthcare, Forchheim) were compared with TOF-MRA-ima…

Modified cryopreservation and xenotransplantation of human parathyroid tissue.

1999

Introduction: A modified cryopreservation technique for human parathyroid tissue was compared with the standard method using a programmed freezer. Methods: Total parathyroidectomy was performed in three groups of 6-week-old Rowett nude rats. Group I (control) underwent no transplantation of parathyroid tissue (n=9). After 10 days, the rats of groups II (n=15) and III (n=15) underwent xenotransplantation of 20 mg cryopreserved human parathyroid tissue, which had been stored in liquid nitrogen at –196°C for 1–22 months prior to xenotransplantation. The parathyroid tissue was derived from 15 parathyroidectomized patients with renal hyperparathyroidism. Two tissue samples were obtained from eve…

In vitro evaluation of the biocompatibility of contaminated implant surfaces treated with an Er : YAG laser and an air powder system

2004

Abstract: Titanium platelets with a sand-blasted and acid-etched surface were coated with bovine serum albumin and incubated with a suspension of Porphyromonas gingivalis (ATCC 33277). Four groups with a total of 48 specimens were formed. Laser irradiation of the specimens (n=12) was performed on a computer-controlled XY translation stage at pulse energy 60 mJ and frequency 10 pps. Twelve specimens were treated with an air powder system. After the respective treatment, human gingival fibroblasts were incubated on the specimens. The proliferation rate was determined by means of fluorescence activity of a redox indicator (Alamar Blue® Assay) which is reduced by metabolic activity related to c…

Transfusion-related acute lung injury after intravenous immunoglobulin treatment in a lung transplant recipient

2012

Three weeks after single-lung transplantation for pulmonary fibrosis, a patient with high serum levels of de novo donor-specific antibodies received high-dose intravenous immunoglobulin (IVIG) infusion (scheduled dose: 2 g/kg on 2 days) to prevent antibody-mediated rejection. Within the first hours after completion of infusions, he experienced acute lung injury involving the transplanted lung. Given the clinical evolution and the absence of an alternative diagnosis, transfusion-related acute lung injury (TRALI) was diagnosed. The IVIG administered on each day was from the same batch. At day 110, because of an increase in the serum titers of donor-specific antibodies, IVIG therapy was reintr…

Treatment of Axillary hyperhidrosis

2022

BACKGROUND Axillary hyperhidrosis characterized by excessive sweating in the axillary regions is a frustrating chronic autonomic disorder leading to social embarrassment, impaired quality of life and usually associated with palmoplantar hyperhidrosis. Identifying the condition and its cause is central to the management. AIM The aim of this article is to discuss treatment options for axillary hyperhidrosis. METHODS Comprehensive literature search using PubMed and Google Scholar was performed to review relevant published articles related to diagnosis and treatment of axillary hyperhidrosis. RESULTS Treatment modalities for axillary hyperhydrosis vary from topical and systemic agents to inject…

Orthotope arterialisierte Lebertransplantation bei Ratten mit Stenttechnik der supra- und infrahepatischen v. cava

2003

The aim of this study was to establish a liver transplant model with a reduced warm ischemic period between cold preservation and completed anastomosis. Male brown Norway rats were used. A cuff was fixed in the portal vein, stents were inserted in the A. hepatica, the suprahepatic and infrahepatic v. cava and in the bile duct. After cross clamping of the recipient liver, another stent, occluded by a small pin, was introduced in the recipient suprahepatic v. cava. After ligation of this recipient suprahepatic caval stent the recipient liver was removed and the cold prepared donor liver was pushed forward along the pin and both suprahepatic stents of recipient and donor were connected. Then c…

Outcomes of Mismatched Related Allogeneic Stem Cell Transplantation for Chronic Lymphocytic Leukemia: A Retrospective Study on Behalf of the Chronic …

2016

Abstract Introduction: Allogeneic hematopoietic stem cell transplantation (HCT) is a treatment for CLL that can give long disease control. Even with the availability of kinase and BCL2 inhibitors, HCT is still performed in fit patients (pts) with high-risk CLL. Almost exclusively, outcomes on matched related and unrelated donor transplantations in CLL have been published. Recently, mismatched related donors are gaining interest because of the better outcome of haploidentical HCT with post-transplantation cyclophosphamide (PTCY). Methods: All pts with CLL who received a first allogeneic HCT with a mismatched related donor and whose data were available in the EBMT registry were analyzed. Medi…

Klinische Relevanz der NNH-CT vor Knochenmarktransplantation

1997

PURPOSE To investigate the clinical necessity of CT of the paranasal sinuses before bone marrow or peripheral blood stem cell transplantation. PATIENTS AND METHODS 80 patients with malignant disease underwent coronal CT of the paranasal sinuses prior to transplantation to exclude sinusitis. RESULTS CT revealed sinusitis requesting therapy in 17/80 patients (21%). Patients with leukaemia and non-Hodgkin lymphoma were significantly more affected. Chronic sinusitis was found in two patients, mucosal swelling not requesting therapy in 22, and normal findings in 39. CONCLUSION CT of the paranasal sinuses is advised in patients suffering haemoblastoses with an increased risk of infectious complic…

Updated management of occipital nerve stimulator lead migration: case report of a technical challenge

2021

Abstract Electrode migration is a challenge, even with adequate anchoring techniques, due to the high mechanical stress on components of occipital nerve stimulation (ONS) for headache disorders. When a lead displacement of an ONS implant is diagnosed, there are currently different approaches described for its management. Nevertheless current neuromodulation devices are designed like a continuum of components without any intermediate connector, and if a lead displacement is diagnosed, the solution is the complete removal of the electrode from its placement, and its repositioning through an ex-novo procedure. The described technique can allow ONS leads to be revised while minimizing the need …
